2. Project overview
In order to meet the power needs of industrial users in Karim Meral, Riau Province, Indonesia, the owner PT. Soma Daya Utama plans to build 2 coal-fired power plants with a gross output of 31MW in West Meral. This coal-fired power plant uses low heat. It is worth burning coal, equipped with circulating fluidized bed boilers, condensing steam turbine generator sets, seawater cooling towers and other power plant equipment.

SOMA Karim CFSPP 2 x 31MW power station is located in West Bunker Village, at latitude 010 3'17.36" north, longitude 1030 18'39.75" east, in the West Meral District of Karim Regency Province, Riau Islands. The proposed site is located on the west coast of the central part of Karimun Island, about 200m from the Strait of Malacca to the west, and is a hilly landform. The site is located on the top of the hill, and the overall terrain is high in the middle and low in the surroundings.

The role of this power plant is to provide a source of power for the industrial load center and operate in an isolated grid.
